Provedor de dados: 32
Autores: Lagunes Rivera, Sergio Alberto.
La caprinocultura se desarrolla en el 73% de los municipios del estado de Puebla, a altitudes de 900 a 3,000 msnm, donde las condiciones ambientales pueden influir en la presencia de parasitosis. El objetivo del estudio fue determinar la prevalencia de parásitos gastrointestinales e identificar los géneros de nematodos que afectan a los caprinos, en función de tres estratos fisiológicos de los animales y de tres zonas climáticas. El muestreo se realizó en 49 rebaños ubicados en municipios con importancia caprina, los cuales se agruparon en tres zonas en función de su altitud, temperatura y precipitación. En cada rebaño se muestrearon tres estratos de animales: hembras primalas, adultas y sementales, colectando respectivamente, 236, 262 y 50 muestras de 20...

Influence of biotic and abiotic factors on the metazoan parasite communities of a native prey fish: study in 28 Andean Patagonian lakes
Provedor de dados: 67
Autores: Fernandez,Valeria; Garibotti,Gilda; Semenas,Liliana; Viozzi,Gustavo.
Galaxias maculatus (small puyen) is a prey fish which plays a main role in lake food webs of Patagonia. Previous studies, at local scale, have shown that the richness and composition of parasitic metazoan component communities associated to G. maculatus in a group of small shallow lakes in the surroundings of the Nahuel Huapi Lake, are affected by the composition of the native fish assemblage in each lake. The aims of this work were: a) to characterize the helminth community of G. maculatus at regional scale, including data of 28 Andean lakes of the Neuquén and Río Negro Provinces, and b) to identify biotic and abiotic factors of these lakes influencing the occurrence and prevalence of the different helminth species parasitizing this highly abundant and...

У 3 видов черноморских гребневиков - Mnemiopsis leidyi Agassiz, 1865, Beroe ovata Mayer, 1912 и Pleurobrachia pileus Müller,1776 в настоящее время зарегистрирован только один вид паразита - нематода Hysterothylacium aduncum (Rud.,1802), представленная личинками  III - IV стадии развития. M. leidyi и B. ovata являются случайными хозяевами для H. aduncum. Высокая зараженность P. pileus данным паразитом указывает на его участие в  жизненном цикле нематоды в качестве дополнительного хозяина.

Effect of temperature changes on the cercarial-shedding rate of two trematodes
Provedor de dados: 76
Autores: Achiorno,Cecilia L.; Martorelli,Sergio R.
ABSTRACT Since temperature is a key condition in the initiation of cercarial emergence, the objective of the work reported here was to evaluate the effect of that variable on the shedding of two morphologic and taxonomic types of cercariae. Bioassays were accordingly performed with snails naturally infected with either monostome or pleurolophocercous cercariae because those two cercarial types were found to be the most prevalent in the environment under study. The snails were placed in 6-ml circular plastic dishes with soft plastic stoppers containing 3 ml of reconstituted water and then sequentially exposed for 24 h to a 14:10-h light:dark cycle at 20, 25, or 30 °C. The data were analyzed at a significance level of p &lt;0.05 by means of the InfoStat...

Os fitonematoides estão entre os principais problemas fitossanitários da cultura do algodoeiro no Brasil. Em geral, os problemas associados à presença desses parasitas são intensificados por práticas inadequadas do sistema de cultivo, como o uso contínuo e intensivo das áreas cultivadas com culturas hospedeiras suscetíveis, que propiciam um rápido aumento da população desses parasitas, associadas ao trânsito de máquinas e implementos agrícolas entre diferentes áreas, as quais facilitam a rápida dispersão desses organismos nas áreas de cultivo.

In Brazil as in the rest of the world, sectors of production and commercialization of animal originated foods, are changing to attend the two highst marcket demands: competitivity and quality. These exigencies are specially related to healthy foods. So the use of products that leave residues in meat and/or milk is going to be more restritive in an animal production system pointed to sustentability with lower environmental risks. Factors such as: pasture seasonal fluctuations, nutricional defficiencies, management conditions, high parasites incidence and general diseases contribuited to reduction of production and productivity of bovines.

The SAR group (Stramenopila, Alveolata, Rhizaria) is one of the largest clades in the tree of eukaryotes and includes a great number of parasitic lineages. Rhizarian parasites are obligate and have devastating effects on commercially important plants and animals but despite this fact, our knowledge of their biology and evolution is limited. Here, we present rhizarian transcriptomes from all major parasitic lineages in order to elucidate their evolutionary relationships using a phylogenomic approach. Our results suggest that Ascetosporea, parasites of marine invertebrates, are sister to the novel clade Apofilosa. The phytomyxean plant parasites branch sister to the vampyrellid algal ectoparasites in the novel clade Phytorhiza. They also show that...

Environmental factors contributing to the development of brown muscle disease and perkinsosis in Manila clams (Ruditapes philippinarum) and trematodiasis in cockles (Cerastoderma edule) of Arcachon Bay
Provedor de dados: 5
Autores: Binias, Cindy; Do, Van Tu; Jude-lemeilleur, Florence; Plus, Martin; Froidefond, Jean-marie; De Montaudouin, Xavier.
The aim of the present study was to identify environmental factors that could explain the distribution of different pathologies of commercially exploited intertidal bivalves in an Atlantic lagoon, Arcachon Bay. In particular, the role of the salinity gradient as a driver was explored. The Manila clam Ruditapes philippinarum experienced two severe pathologies, perkinsosis, which is due to a protozoan parasite, and brown muscle disease (BMD), the etiological agent of which remains unknown. Perkinsus olseni infection was very low in a small low-salinity area but, at the scale of the entire lagoon, was more influenced by organic matter content in the sediment and by emersion time. BMD prevalence was also 2.6 times higher in the higher organic content area but...

Ascophrys rodor (Campillo and Deroux) parasite of the reared common prawn P. serratus).
Provedor de dados: 5
Autores: Deroux, G.; Campillo, Albert; Bradbury, Ph. C.
A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical...

Autores: Cochennec, Nathalie; Le Roux, Frédérique; Berthe, Franck; Thebault, Anne.
Bonamiose, a disease caused by the protozoa Bonamia ostreae, has destroyed the flat oyster Ostrea edulis production, in France but also in Europe and in the United States since 1979. Another species of Bonamia has been monitored in New-Zealand, in Australia and lately in Chile. In Canada and Australia, two other parasites have been described in cupped oyster: Mikrocytos mackini and Mikrocytos roughleyi. All these small size protozoa are grouped under the name "Mikrocell". For most of them, light and electronic microscope descriptions have been realised. Based on those criteria, different taxonomic positions have been proposed. However, these analysis are still questioned today.

Biologie du copepode Lernaeenicus sprattae Sowerby, 1806) et ses actions pathogenes sur les populations de sardines des cotes du  Languedoc-Roussillon.
Provedor de dados: 5
Autores: El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious  effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

Comparison of Solea solea macroparasites between two nursery-continental shelf systems in the Bay of Biscay and the Portuguese coast
Provedor de dados: 5
Autores: Durieux, Eric; Marques, J.f; Sasal, P; Begout, Marie-laure; Cabral, H.
Digenean metacercariae of 0 year group common sole Solea solea (n = 70) were more abundant in the embayed nursery of the Pertuis Charentais than in the Tagus estuary nursery. Macroparasite assemblages of adult sole (n = 119) displayed only one species in common between the Bay of Biscay and the Portuguese coast continental shelves. These data highlighted the potential use of macroparasites as biological tags in various aspects of common sole ecology. (C) 2007 The Authors.

An epidemiological survey was conducted in the Seine estuary and in two smaller and relatively preserved estuaries on the French Atlantic coast in order to estimate the occurrence of liver lesions in European flounder, Platichthys flesus, and also to seek putative risk factors for the recorded pathologies. Four hundred and seventy-eight fish of both sexes and of different size ranges were sampled in the three studied areas, 338 of which in the Seine estuary. All fish were examined for histopathological liver lesions, while DNA adducts and otoliths were analyzed on a subsample. Five categories of hepatic lesions were recorded with the following prevalence for the Seine estuary: 36.7 % inflammations, 8 % parasites (mainly encysted nematodes), 6.5 % foci of...

Dietary studies of marine species constitute an important key to improve the understanding of its biology and of its role in the ecosystem. Thus, prey-predator relationships structure and determine population dynamics and the trophic network at the ecosystem scale. Among the major study sites, the marine ecosystem is submitted to natural and anthropogenic constraints. In the North-Eastern part of the Atlantic Ocean, the Bay of Biscay is a large open area surrounded South by Spain and East by France. This bay is an historic place of intense fishery activities for which the main small pelagic species targeted are the pilchard, Sardina pilchardus and the anchovy, Engraulis encrasicolus. The aim of this work is to analyze the trophic ecology of these two small...

Provedor de dados: 80
Autores: BLA,Verçosa; ACJ,Borges; FJM,Mendes; MLS,Costa; NB,Pereira; MN,Melo; IL,Mendonça; FAL,Costa; AC,Vasconcelos.
The skin has an important role in the transmission of visceral leishmaniasis (VL) as the infection pathway in dogs. To better characterize the inflammatory response of intact skin in VL, sixty infected dogs (30 symptomatic and 30 asymptomatic) and six non-infected controls were studied. Diagnosis of visceral leishmaniasis was confirmed by RIFI and ELISA; direct visualization of the parasite in bone marrow aspirate; imprints of popliteal lymph nodes, spleen, liver and skin; culture in NNN-phase liquid Schneider's medium; and PCR (performed only in the ear skin). Amastigote forms of the parasite in intact skin were found only in symptomatic dogs. Inflammatory infiltrates were observed in all groups, varying from intense and/or moderate in symptomatic to...

Nematodes parásitos como indicadores biológicos en las especies Macruronus magellanicus y Merluccius hubbsi (Pisces, Gadiformes)
Provedor de dados: 20
Autores: Incorvaia, I.S.
Parasites nematodes as biological tags of Macruronus magellanicus (longtail hake) and Merluccius hubbsi (hake) colleted between 34°- 55°S in the SW Atlantic were studied. Adult specimens of Hysterothylacium aduncum, Ascarophis marina and Ichthytofilaria argentinensis, and the third-stage specimens of H. aduncum, Anisakis simplex and Contracaecum aduncum were described. Histological studies showed that I. argentinensis provokes tissue reactions in the swim bladder of  M. hubbsi.  A wide distributional range of species can be represented by many fish populations or fishing stocks. As these can overlap in space, the proper identification of stocks is necessary for fisheries management. The parasitologic method is one currently used to determine stocks....

Autores: De Charleroy, D.; Grisez, L.; Thomas, K.; Belpaire, C.; Ollevier, F.P.
For some years now the parasitic swim bladder nematode &lt;i&gt;Anguillicola crassus&lt;/i&gt; of the European eel &lt;i&gt;Anguilla anguilla&lt;/i&gt; L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...

Abstract Philornis larvae and pupae were collected in nestlings of Neothraupis fasciata (Lichtenstein), the White-banded Tanager (Passeriformes, Thraupidae), in three breeding seasons, between October and November 2003-2005 in a reserve in central Brazil. Here, we present biological data, diagnosis to the recognition of the species and a key to the segregation of species occurring in the Cerrado. The larvae were intradermic in the nestlings and the pupae were collected in the nests after the birds have abandoned them. The immatures collected were taken to the laboratory and reared under laboratory conditions, until emergence. The species identified as Philornis torquans (Nielsen), is here firstly recorded from the Brazilian Cerrado, and firstly recorded...

Abstract: The objective of this work was to evaluate a recirculating aquaculture system using biological aerated filters in tanks for tambaqui (Colossoma macropomum) fingerlings farming, with two initial stocking densities (1.4 and 2.5 kg m-3). The biofilters had similar materials (media) and the same granulometric standards, but inverted orders of the media (classic and inverted). The following were monitored for 90 days: water quality; zootechnical, parasitological, and hematological parameters; and hematimetric indices. Water temperature, oxygen levels, pH, electrical conductivity, and dissolved solids concentration were compatible with tambaqui farming and did not differ between the different biofilters and densities. The ammonia and nitrite value was...

Biology of a trap-nesting wasp of one species the ground-nesting Liris (Hymenoptera: Crabronidae) from the Atlantic Forest of southern Brazil
Provedor de dados: 103
Autores: Costa,Camila Cristina Ferreira da; Buschini,Maria Luisa Tunes.
ABSTRACT Studies on the nesting biology of Liris are restricted to a few notes and observations on ground-nesting species. There are no studies of this kind about Brazilian species. We investigated and described the nesting biology of Liris sp. obtained by trap-nests that were installed at an area of Atlantic Forest vegetation (25°10'S, 48°18'W) in southern Brazil. The nests of Liris sp. are built with a variety of plant debris. They usually have one cell, but may have up to two. Nests do not show vestibular or intercalary cells. Immatures have a hard cocoon made with the silk they produce, mixed with the fine sand and sawdust left by the adult female at the bottom of the cell. No nest parasites were observed. The wasps did not go through diapause at the...

ABSTRACT Austrodiplostomum compactum is a digenetic trematode whith metacercariae that occur in the eyes of a wide variety of fish species. In Brazil, A. compactum metacercariae have been reported in many fish species, but there are only a few studies in the Amazon region. Due to the lack of information in the Amazon, the aim of this study was to report the occurrence of A. compactum metacercariae in the eyes of 15 specimens of Plagioscion squamosissimus from the Lake Catalão, in Amazonas, Brazil. Fishes were collected using gill nets placed randomly in the lake, euthanized in a field laboratory, and had their eyes dissected and examined under a stereomicroscope. A total of 801 metacercariae were registered infecting the eyes of the hosts with a parasitic...

ABSTRACT A helminthological examination was carried out on 14 specimens of Eucinostomus melanopterus (flagfin mojarra) and 19 Eugerres plumieri (striped mojarra), of which a total of 461 helminths were collected. As a result, and 12 taxa were registered (five species, five genus and tow family), as follows: four monogeneans, five digeneans (four adults, one metacercaria), one cestode (larva) and tow nematodes (larvae). The highest prevalence was for Neodiplectanum mexicanum (29 %) infecting E. melanopterus and Aristocleidus hastatus (37 %) infecting E. plumieri. Both hosts shared 50 % of recorded species, and none of the identified helminthes represents a zoonotic risk.

ABSTRACT The aim of this study was the identification of Leishmania species that causes cutaneous leishmaniasis in a patient from Buenaventura, Valle del Cauca, on the Pacific coast of Colombia. Clinical samples were obtained from a 29 years-old male who presented a distinct ulcer with raised borders on his neck. Samples were taken for direct microscopic examination, parasite culture, and molecular identification of the infecting Leishmania species by sequencing of the cytochrome b gene. Direct examination was positive for amastigotes of Leishmania but the culture was negative. The infecting parasite species was identified as L. (V.) guyanensis by means of the nucleotide sequence of a 509 bp fragment of the cytochrome b gene. We report the presence of L....

Importance of CD8 T cell-mediated immune response during intracellular parasitic infections and its implications for the development of effective vaccines
Provedor de dados: 42
Autores: Rodrigues,Mauricio M.; Boscardin,Silvia B.; Vasconcelos,José R.; Hiyane,Meire I.; Salay,Gerson; Soares,Irene S.
Obligatory intracellular parasites such as Plasmodium sp, Trypanosoma cruzi, Toxoplasma gondii and Leishmania sp are responsible for the infection of hundreds of millions of individuals every year. These parasites can deliver antigens to the host cell cytoplasm that are presented through MHC class I molecules to protective CD8 T cells. The in vivo priming conditions of specific CD8 T cells during natural infection are largely unknown and remain as an area that has been poorly explored. The antiparasitic mechanisms mediated by CD8 T cells include both interferon-g-dependent and -independent pathways. The fact that CD8 T cells are potent inhibitors of parasitic development prompted many investigators to explore whether induction of these T cells can be a...

Towards an understanding of the interactions of Trypanosoma cruzi and Trypanosoma rangeli within the reduviid insect host Rhodnius prolixus
Provedor de dados: 42
Autores: Azambuja,Patrícia; Ratcliffe,Norman A.; Garcia,Eloi S.
This review outlines aspects on the developmental stages of Trypanosoma cruzi and Trypanosoma rangeli in the invertebrate host, Rhodnius prolixus. Special attention is given to the interactions of these parasites with gut and hemolymph molecules and the effects of the organization of midgut epithelial cells on the parasite development. The vector insect's permissiveness to T. cruzi, which develops in the vector gut, largely depends on the host nutritional state, the parasite strain and the molecular interactions with trypanolytic compounds, lectins and resident bacteria in the gut. T. rangeli invades the hemocoel and once in the hemolymph, can be recognized and activates the defense system of its insect vector, i.e., the prophenoloxidase system,...

Provedor de dados: 42
Autores: DIAS,KARINA G.A; ALVES,CARLOS A.; SILVA,REINALDO J. DA; ABDALLAH,VANESSA D.; AZEVEDO,RODNEY K. DE.
ABSTRACT The parasites are indicative of several biological aspects of their hosts, including their diet, migration, recruitment and phylogeny, but they can also be direct indicators of the environmental quality. Hoplosternum littorale is a fish that has a high commercial value in some South American countries. The fishes were collected from January to July 2012, in two locations of the Peixe River in the municipality of Anhembi, State of São Paulo, Brazil, which had different environmental and limnological characteristics (river mouth and Lagoa Cabeça de Boi). An amount of 30 fish specimens were captured in each location for the analysis of their parasitic fauna. Nine species of metazoan parasites were collected. Both Brillouin`s diversity index and...

Autores: Chung,Sang Wan; Kim,Yee Hyung; Lee,Eun Jung; Kim,Dae Hyun; Kim,Gou Young.
Sparganosis in humans is an incidental infection and is known to be associated with eating insufficiently cooked meat of frogs and snakes or drinking unboiled stream water. Although it can involve various internal organs, pulmonary and pleural involvement due to sparganum is rare. Because we recently experienced two cases involving lung parenchyma and pleura that were misdiagnosed as bacterial pneumonia and lung cancer, we herein intend to present them in detail.

Sloth biology: an update on their physiological ecology, behavior and role as vectors of arthropods and arboviruses
Provedor de dados: 56
Autores: Gilmore,D.P.; Da Costa,C.P.; Duarte,D.P.F.
This is a review of the research undertaken since 1971 on the behavior and physiological ecology of sloths. The animals exhibit numerous fascinating features. Sloth hair is extremely specialized for a wet tropical environment and contains symbiotic algae. Activity shows circadian and seasonal variation. Nutrients derived from the food, particularly in Bradypus, only barely match the requirements for energy expenditure. Sloths are hosts to a fascinating array of commensal and parasitic arthropods and are carriers of various arthropod-borne viruses. Sloths are known reservoirs of the flagellate protozoan which causes leishmaniasis in humans, and may also carry trypanosomes and the protozoan Pneumocystis carinii.

Apoptosis in parasites and parasite-induced apoptosis in the host immune system: a new approach to parasitic diseases
Provedor de dados: 56
Autores: Barcinski,M.A.; DosReis,G.A.
Apoptosis, a form of programmed cell death (PCD), has been described as essential for normal organogenesis and tissue development, as well as for the proper function of cell-renewal systems in adult organisms. Apoptosis is also pivotal in the pathogenesis of several different diseases. In this paper we discuss, from two different points of view, the role of apoptosis in parasitic diseases. The description of apoptotic death in three different species of heteroxenic trypanosomatids is reviewed, and considerations on the phylogenesis of apoptosis and on the eventual role of PCD on their mechanism of pathogenesis are made. From a different perspective, an increasing body of evidence is making clear that regulation of host cell apoptosis is an important factor...

We examined samples of irrigation water and vegetables from kitchen gardens in Campinas, Brazil. The bacterial analysis condemned 22.3% of the vegetable samples, and the parasitological examination condemned 14.5%. The criteria established by the Brazilian legislation condemned 11.8% of the irrigation water samples. Parasites were significantly more frequent in vegetables in the rainy season, while excessive fecal coliforms were more frequent in the dry season. A proper monitoring of the irrigation water supply is important to avoid the contamination of vegetables.

ABSTRACT: Liquid pig manure (LPM) is widely used as a compost fertilizer for vegetable crops destined for human consumption. However, these wastes may contain parasites eggs, such as the nematode Ascaris suum, that pose serious health risks to humans. We attempted to determine the most appropriate technique for recovering A. suum eggs from LPM compost. Samples were collected from two waste sources during composting, including 23 samples containing LPM, sawdust, and wood shavings, and 14 samples of LPM alone-both in triplicate. Samples were analyzed using several different recovery methods. Recovery of eggs by the modified Bailenger method with adaptations was significantly more effective and recovered 57% more eggs than by the modified Bailenger method...
